Head Voloshynovskyi Anatolii S., Доктор фізико-математичних наук Registration Date 08-04-2026 Organization Ivan Franko National University of Lviv popup.description1 Elucidation of the mechanisms of luminescent and scintillation processes and approaches for the development of fast scintillators based on halide perovskites. The work is aimed at solving tasks and problems in the field of high-energy physics, environmental radiation monitoring, and nuclear medicine. popup.description2 Single crystals of non-activated halide perovskites CsPbCl₃, CsPbBr₃, and CsSnBr₃ were grown from the melt using the Stockbarger method. A concentration series of CsPbCl₃ single crystals activated with ns²-element ions (Mg, Ca, Sr) and lanthanide ions (Ce, Pr, Eu, Yb), as well as CsPbBr₃ crystals activated with Cd ions, were grown. Single crystals of CsPbBr₃ perovskites were also grown by the precipitation method. X-ray structural studies of the crystals were carried out using DRON-2M and STOE Stadi P X-ray diffractometers. The crystal growth technique ensures their single-phase composition. The chemical composition of the samples and the impurity concentration were determined using energy-dispersive X-ray fluorescence analysis. A decrease in the lattice parameters of the perovskites was observed upon activation with metal cations whose ionic radii are smaller than that of lead, as well as a decrease in the Pb–Cl distance. Approaches to nanoparticle compaction were developed. Pure CsPbCl₃ and CsPbBr₃ nanoparticles, as well as nanoparticles activated with Cd²⁺ and Sr²⁺ ions, were synthesized and compacted into polymer matrices and metal–organic frameworks.
